It's different for every business but typically a CEO is the visionary, strategic leader of the company while the president leads the day-to-day operations.

If Github started selling insurance, there's a good chance they would have a president for Github Code and a president for Github Insurance. They wouldn't have two CEO's, though.

How would you characterize the COO then?

[erichocean]

COOs manage the day-to-day operations.

What's the difference between "leading" day to day operations and "managing" them?

[goldenkey]

I know SC2 is probably a poor example but it fits very well here. It's the difference between managing a team strategy in an RTS versus looking at the individual unit deaths/spawns, types of units, etc.

The two are similar, and you'll often see them combined. For the most part, president pre-dates the CXO nomenclature. Before there were CEOs, COOs, and CFOs, there were Chairmen, Presidents, and Treasurers. Those titles/roles still exist, but are often merged with CXO functions.
